Analog - Digital - Converter
AWA/2X12B
1. Introduction
The analog - digital - converter AWA/2X12B is used as an input module for the electric camswitches of
the CamCon series. The converter has two independent voltage - (-10V - +10V respective 0 - +10V) or
power inputs (0 - 20mA) with a resolution of 12Bit, that can be connected via a 6 pole datacable to the
external interface of the CamCon devices DC50/561, 90 and 115. By switching several devices in
series connection it is possible to connect up to 5 AWA/2X12B analog digital converters.
2. Assembly
The device is clip-locked onto an "EN carrier rail" in the switchboard (see also chapter
"6.3. Calibration" on page 8). The grounding pins and cable mantlings are to be put on the
shortest way possible onto serial grounding clip next to the device. The grounded
assembly plate and its electrical connection to the "EN carrier rail" allow an excelent
grounding of the disturbances onto the covering. All cable connections are to be switched
in a cold state ! The external interface of the CamCon (e.g. DC16/50/90 or DC115) is
connected with a cable of the type: KKyy/IO-XX (yy = CamCon Type / XX = length in
meters) to the plug "external interface IN" or "ext.Int. IN" on the module. Every other
device is connected to the plug "external interface OUT" or "ext.Int. OUT" with a cable
of the same type. The data lines of the external interface have to be galvanically
separated with an optical coupler, they have to be placed and covered separately and the
cover has to be grounded on both ends. Analog signals have to be placed and covered
separately and the cover has to be grounded on one end. The supply voltage has to be
connected separatly for every module and measures 24V DC +/-20%.
Note:
example
The analog - digital - converter has to be switched to the end of the interface row.
3. Status LED
The analog - digital - converter has 2 status LEDs (see also chapter 6.3. Calibration).
LED 1
LED 2
indicates the presence of supply-power.
indicates that no data exchange via a CamCon DC50, 90 or DC115CamCon is done.
Possible causes are: The cable length adjusted at the CamCon outruns the maximum length
of 300 meters, the CamCon DC50, 90 or DC115 is switched off, i.e. the data exchange is
interrupted (broken wire).

5.4. Pin allocation of the external interface
The analog - digital - converter AWA/2X12B has an external interface via which the data transfer with
the CamCon device is done. Via the interface input the data exchange with the CamCon e.g.
DC16/50/90 or DC115 is done. Via the interface output, the data exchange with another analog - digital
- converter or a CamCon DC91 output-expansion is done. By this series connection several devices
may be connected to a CamCon. A shielded 6 pole data cable with conductors wired in pairs is
required. The maxium wiring disatance is 300 meters, the data exchange is done potentially free via
optical couplers.

6. Configuration
.
6.1. Change the input - signal level
The analog inputs' signal level can be changed by solding bridges on the solder side of the
AWA/2X12B's printed circuit board.
The following input signals can be set: "0-20mA", "-10V - +10V" or "0 - +10V".
The adjusted signal level is marked for every input by with a cross on the metal cap.
To change the input level, detach all cable connections from the device.,
remove the device from the switch chest, open the floor part at the devices
side using a screwdriver and pull the printed circuit board out of the floor
part. On the solding side of the printed circuit board are to solding bridges
for signal input 1 and 2 which are called SJ1 to SJ4 in the drawing. Via SJ1
and SJ" the signal level for input 1 and via SJ3 to SJ4 for input 2 are set.
Having adjusted the desired signal level, the input switching has to be
equalized anew. See also chapter "6.3. Calibration" on page 8.
6.1.1. Solding bridge SJ1
To switch the 1st analog input from unipolar (0V - 10V) to the bipolar (-10V
- +10V) voltage measuring the solding bridge SJ1 has to be closed. This solding bridge may only be
closed, if the solding bridge SJ2 is open.
6.1.2. Solding bridge SJ2
To switch the 1st analog input from voltage - to currency input, the solding bridge SJ2 has to be closed.
6.1.3. Solding bridge SJ3
To switch the 2nd analog input from voltage - to currency input, the solding bridge SJ3 has to be
closed.
6.1.4. Solding bridge SJ4
To switch the 2nd analog input from unipolar (0V - 10V) to the bipolar (-10V - +10V) voltage measuring
the solding bridge SJ4 has to be closed. This solding bridge may only be closed, if the solding bridge
SJ3 is open.
6.2. Reference voltage supply
Two intern voltages (+4.096 and +5V) are avaible, an external voltage source may be
enabled by switching them both of. The choice is made via a jumper ledge on the
component side of the printed circuit board. To change the reference voltage, remove
the cap by unscrewing the four cap nuts and choose your voltage source at jumper
JP1.
Bridge at 1+2
Bridge at 2+3
= +5V
= +4.096V
Bridge open
= external
Note:
Ref. voltage from the operating voltage.
Ref. voltage by precission voltage controller
(default).
Ref. voltage external by at least +1V to a maximum of +5V.
If the source of reference voltage is changed, the input switching has to be equilibrated
anew. (see also chapter "6.3. Calibration").

6.3. Calibration
If the AWA/2X12B module has to be eliquibrated anew,
remove the case's top by unscrewing the four cap nuts,
to get to the pontentiometer. Four multi-gear trimmer are
provided for this purpose. These are:
R36
R37
= Amplification input 1
= Offset input 1 at ± 10V input.
R39
R40
= Amplification input 2
= Offset input 2 at ± 10V input.
6.3.1. Calibration during power input
Set a constant power source at clamps 5 and 6 for input
1 or at clamps 8 and 9 for input 2. The value of currency
has to be known with great accuracy. It should be in the range of 15 to 20 mA. Now choose the menu
in which this value is displayed in the device (CamCon). You are able to increase this displayed value
by turning to the left at the R36 (input 1) or R39 (input 2) or de-crease it by turning to the right. Set the
now present current or it's corresponding value and seal the potentiometer with sealing wax. At the
potentiometers atR37 and R40 no configuration can be done while being under current.
6.3.2. Calibration during voltage-input 0 - +10V
Set a voltage source to the terminals 5 and 6 for input 1 or 8 and 9 for input 2. The value of voltage has
to be known with great accuracy. It should be in the range o+5 to +10 Volt. Now choose the menu in
which this value is displayed in the device (CamCon).You are able to increase this displayed value by
turning to the left at the R36 (input 1) or R39 (input 2) or de-crease it by turning to the right. Set the
now present voltage or it's corresponding value and seal the potentiometer with sealing wax or Tip-EX.
At the potentiometers atR37 and R40 no configuration can be done while being under a voltage about
0 to +10 Volt.
6.3.3. Calibration during voltage-input -10V - +10V
Bypass the terminals 5 and 6 for input 1 or 8 and 9 for input 2 using a wire with a length of 5cm and
choose the menu in which this value is displayed in the device (CamCon). Now set the dislay-value to 0
by turning to the left or right at R37 (input 1) or R40 (input2). Then seal the potentiometer with sealing
wax or Tip-EX.
Now set a voltage source to the terminals 5 and 6 for input 1 or 8 and 9 for input 2. The value of
voltage has to be known with great accuracy. It should be in the range o+5 to +10 Volt. Now choose
the menu in which this value is displayed in the device (CamCon). It should be in the range o+5 to +10
Volt. Now choose the menu in which this value is displayed in the device (CamCon).You are able to
increase this displayed value by turning to the left at the R36 (input 1) or R39 (input 2) or de-crease it
by turning to the right. Set the now present voltage or it's corresponding value and seal the
potentiometer with sealing wax. If the voltage source is potentially free towards the AWA/2X12B, you
are able to reserve the polarity of the voltage at the terminals 5 + 6 or 8 + 9. The display now should
show the negative value of the same size as it was the positive before.
